To save a lot of patching for the regression tests in the devel/got port, I added this shell function: # compat wrapper sed() ( for i; do arg=$1 shift case $arg in -i) set - "$@" "$arg" '' ;; *) set - "$@" "$arg" ;; esac done exec sed "$@" ) No, it doesn't handle all cases, but it is good enough in that context. ports/devel/got/files/patch-regress_cmdline_common.sh -- Christian "naddy" Weisgerber naddy@mips.inka.de
